Thanks for this patch. However, after reading this, I have a stupid
question: which file system should I use if I had to reinstall my
computers from scratch now?
Ext3 means either hardware that supports barriers (not sure how to
check, and anyway I have to use encryption on the work laptop due to the
corporate policy) or disabling write cache (but, as Alan Cox said, this
shortens the lifespan of the disk). Does this requirement apply to other
journaling filesystems? Do I need journaling at all, given that I have
an UPS on my desktop and a battery in the laptop?
